SEGUIN, Texas – A man was arrested after Guadalupe County investigators executed a search warrant tied to an online child exploitation investigation that began with a tip to the National Center for Missing and Exploited Children, according to the Guadalupe County Sheriff’s Office.
The sheriff’s office said that on 7/23/2026, the Guadalupe County Sheriff’s Office Internet Crimes Against Children Unit executed a search warrant at a residence in the 1400 block of Barnes Drive in Seguin. As a result of the search and investigation, the sheriff’s office said Robert “Bobby” Castillo was arrested for Possession or Promotion of Child Pornography and transported to the Guadalupe County Adult Detention Center.
The sheriff’s office said the investigation stemmed from a cyber tip received from the National Center for Missing and Exploited Children.
“We have made an ongoing commitment to protecting the children in our county. Our message has been made loud and clear. For those pursuing our children online to hurt or exploit them, we are hunting you. We will not tolerate that behavior in Guadalupe County. Your choice is simplemove or prison,” Sheriff Joshua Ray said.
The sheriff’s office encouraged anyone who suspects a child is being exploited or groomed online to report it to the NCMEC CyberTipline at CyberTipline.org or 1-800-843-5678, or contact the GCSO ICAC Unit directly.
